Write a program to insert and deletion of an element at/from Kth position in an array

#include<iostream.h>

 #include<conio.h>

 void main()

 {

 int n,a[20],i,item,j,loc;

 clrscr();

 cout<<"enter the size of array:-"<<endl;

 cin>>n;

 cout<<"\nEnter the elements of the array:-"<<endl;

 for(i=1;i<=n;i++)

            cin>>a[i];

 cout<<"\nEnter the element :-"<<endl;

 cin>>item;

 cout<<"Enter the location where u want to insert:-"<<endl;

 cin>>loc;

 for(j=n;j>=loc;j--)

             {

              a[j+1]=a[j];

             }

  n=n+1;

  a[loc]=item;

  cout<<"After insertion of a element:-"<<endl;

  for(i=1;i<=n;i++)

            {

  cout<<"\n"<<a[i];

              }

            cout<<"Enter the location where from where u want to delete:-"<<endl;

 cin>>loc;
